EDWVIN B. HAWVKINS, OF SAN FRANCISCO, CALIFORNIA.

DIE-LIFTER.

SPECIFICATION forming part of Letters Patent No. 766,694, dated August2, 1904.

Application filed October 28,1903. Serial No. 178,942- (No model.)

To (LU whom it may concern.-

Be it known that I, EDWIN B. HAWKINS, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in Die-Lifters,of which the following is a specification.

My invention relates to means for lifting a die from its mortar, thusavoiding the necessity of removing the die from the mortar by hand; andthe object of the invention is to save time and labor in the handling ofdies.

The device hereinafter described, and shown in the drawings, is alsoadapted for use in lifting pots of molten metal and in similar work, andI do not wish to limit its use to dies alone.

My invention consists of the novel features of construction andcombination of parts hereinafter described, particularly pointed out inthe claims, and shown in the accompanying drawings, in which Figure 1is: an outline view, in side elevation, showing the manner of using mydevice. Fig. 2 is a perspective view of the lifter as in use, a portionof the handle being broken off. Fig. 3 is a side elevationillustratingthe handle at the angle required for releasing the die. Fig.A is a detail view showing the serrated inner end of the handle out ofengagement with the die. Fig. 5 is a similar view showing the inner endof the handle in engagement with the side of the die.

In the drawings, A represents a mortar of any suitable kind or anyreceptacle in which a die or vessel may be placed. On an overhead trackB travels a carriage B. By means of the pulleys B, cable B and the hook13* an object may be lifted above the floor and the carriage run to theplace where it is desired to deposit the object, which can then belowered. This is a well-known construction and is shown to illustratethe practical use of my lifting device.

The device proper consists of a circular band of metal C, having anundercut or beveled inner edge, as shown at C. This band is cut and theends turned outward, as shown at C and between these ends is pivoted thelower portion of a handle or lever D. This lever curves upwardly andoutwardly and terminates in the straight handle portion D. At its lowerinner end it is serrated or toothed, as shown at D A metal loop or bandE is arranged on the inner portion of the handle part adjacent the outerend of the curved portion and nearer to the pivotal point than to theextreme outer end of the handle portion D. A ring E is secured in theloop and is adapted to be engaged by the hook 13*.

In use the band C is slipped over the cylindrical die F, the handlebeing held ina raised position, throwing the lower serrated end out ofengagement with the die. As soon as the band C has reached the properposition the handle is pressed downward, forcing the serrated portion ifof the lever into engagement with the die. The handle is held in thisposition and the die lifted from the mortar and conveyed to the properplace by means of the pulleys, cable, and carriage, the pressure of theserrated end of the lever preventing the die from slipping through theband, the die being held between this lower end of the lever and theupper inner sharp edge of the band, as shown in Fig. 3, and it will benoted in this connection that the lever engages the die at a point belowthe band.

As before stated, this device can be used for lifting other objects thandies.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A device of the kind described comprising a metal band adapted toencircle a die, and a lever pivoted to said band and having a lowerserrated end adapted to engage the die at a point below the band.

2. A device of the kind described comprising a circular band, said bandbeing cut and the ends turned outward, a lever having a lower serratedend and an upper straight handle portion said lever being pivotedbetween the ends of the band at a point adjacent its lower end, meanssecured to the lever inter the pivotal point being adjacent the lowerend of the lever, and means for lifting said lever 10 vertically,substantially as described.
